Suspension of anchor bolts

Abstract

A self-checking anchor bolt suspension assembly includes an array of suspension segments each including equally sized openings distributed in a spaced relationship therein for engaging in suspension resilient tubular caps provided with annular tapered cavities communicating through annular apertures at the lower ends thereof. The aperture size and the cavity taper are selected so that the threaded shank of an anchor bolt of only a singular dimensional increment is receivable and resiliently grasped therein and the caps are each color coded in accordance with the shank size of the bolt. In this manner the color coding provides a quick visual assurance that only the properly sized anchor bolts are deployed for immersion into the poured concrete.

Description

REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of my prior U.S. patent application Ser. No. 11 / 823,324 filed Jun. 27, 2007, now U.S. Pat. No. 7,487,597 and the benefit of this earlier filing date is claimed for all matter common therewith.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to concrete form framing and positioning structures, and more particularly to a method and apparatus for suspending into concrete forms and securing in such suspension anchor bolts for immersion into the poured concrete.[0004]2. Description of the Prior Art[0005]Pouring wet concrete into temporary forms that determine its eventual shape is a process that occurs with substantial frequency in the course of virtually all construction. In each instance, form integrity against distortion by the weight of the wet concrete and the correct placement retention of various anchors that are to be captured in the hardened concrete are...

AI Technical Summary

Benefits of technology

[0009]Accordingly, it is the general purpose and object of the present invention to provide an anchor bolt suspending structure that is also useful to brace the concrete form, that is sized and visually identifiable in coordinated association with several anchor bolt sizes, and that is easily affixed to and removed from both the concrete form and the monolithic pour containment perimeter

[0010]Other objects of the invention are to provide an anchor bolt suspending combination that protects the exposed threads thereof from inadvertent coating by wet cement.

[0016]Thus, for example, a segment that is drilled to accept anchor bolts of a 1 and ¼ inch shank can be color coded bright yellow, a 1 inch shank may be color coded orange, a ⅞ inch shank color coded green, and so on. A set of polymeric, resiliently deformable split tube retainers are then useful to be positioned onto the threaded portions of the anchor bolt shanks that are inserted into the appropriate openings and project above the segment, grasping the bolt shank by resilient compression against the threads formed thereon. The resulting radial dimension increased by the thickness of the mounted retainer results in dimensional interference with the opening, thus effecting a suspending dimensional interference for the received bolt. Of course, once properly positioned the resilient retainers also shield the bolt threads from splashing by the poured concrete.

[0022]Once the coordinated details are observed the worker can then safely affix the complement to the form by driving double-headed nails through corresponding nail holes formed in each segment. These conveniences that the invention provides are not just useful in large construction projects, but are also useful to guide a novice along the rigorous path of proper construction practice.

Problems solved by technology

In each instance, form integrity against distortion by the weight of the wet concrete and the correct placement retention of various anchors that are to be captured in the hardened concrete are matters of constant concern as cured concrete is absolutely unforgiving of all oversights and mistakes.

In large building projects this inattention to inspection convenience tends to raise labor costs as employees and equipment stand by to allow the inspectors to finish their job.
